Coherent shift of localized bound pair in Bose Hubbard model
L. Jin, B. Chen, Z. Song
Based on the exact results obtained by Bethe ansatz, we demonstrate the existence of stable bound pair (BP) wave packet in Bose Hubbard model with arbitrary on-site interaction U.…
Dynamical symmetry of Dirac hydrogen atom with spin symmetry and its connection with Ginocchio's oscillator
Fu-Lin Zhang, Bo Fu, Jing-Ling Chen
The Dirac hydrogen atom with spin symmetry is shown has a SO(4) symmetry. The generators are derived, and the corresponding Casimir operator leads to the energy spectrum naturally.…
Proposed all-versus-nothing violation of local realism in the Kitaev spin-lattice model
Ming-Guang Hu, Dong-Ling Deng, Jing-Ling Chen
We investigate the nonlocal property of the fractional statistics in Kitaev's toric code model. To this end, we construct the Greenberger-Horne-Zeilinger paradox which builds a dir…
Geometric interpretation for A-fidelity and its relation with Bures fidelity
Zhihao Ma, Fu-Lin Zhang, Jing-Ling Chen
A geometric interpretation for the A-fidelity between two states of a qubit system is presented, which leads to an upper bound of the Bures fidelity. The metrics defined based on t…
Exact Solution of a Yang-Baxter Spin-1/2 Chain Model and Quantum Entanglement
Ming-Guang Hu, Kang Xue, Mo-Lin Ge
Entanglement is believed to be crucial in macroscopic physical systems for understanding the collective quantum phenomena such as quantum phase transitions. We start from and solve…
Berry phase and quantum criticality in Yang--Baxter systems
Jing-Ling Chen, Kang Xue, Mo-Lin Ge
Spin interaction Hamiltonians are obtained from the unitary Yang--Baxter -matrix. Based on which, we study Berry phase and quantum criticality in the Yang--Baxter system…
